Description

Technical Field

[0001] This invention belongs to the technical field of aerial work equipment for power transmission lines, specifically relating to a self-locking pulley for attaching and unloading unmanned aerial vehicles (UAVs) for power transmission lines. Background Technology

[0002] When working at heights, due to location constraints, an efficient transportation system is needed to transport various tools and materials to the work position. Typically, this is done using pulleys. The pulleys and their installation methods are mainly of two types: 1. Single-sided pulley: The operator needs to carry the pulley out of the conductor wire to the work position for installation. This process is physically demanding, and the pulley and the lower insulating rope significantly affect the operator's center of gravity, posing a high safety risk. Dismantling also requires the operator to go out of the conductor wire to remove the pulley and carry it back to the tower. Furthermore, once installed, the traditional single-sided pulley is fixed in place and cannot be moved, making it unsuitable for multi-point operations along the same line; 2. Double-ended pulley: The operator carries the pulley to the tower and then uses an operating lever to attach it to the conductor wire, with a spring for locking. To prevent the conductor and ground wire from coming loose, ground personnel then move the pulley to the work position by dragging the insulating rope. In actual operation, due to the weight of the double-headed pulley and the lower rope, the operating rod may be severely bent or even broken when it is too long. This method is only suitable for transmission lines with a small number of insulator discs. In addition, the opening of the double-headed pulley is small, which can cause obstruction. The hanging operation requires high precision and is difficult. Furthermore, the lower pulley uses a movable connection method and can rotate freely, which makes the lower rope easy to twist. To prevent it from coming loose, the locking tongue uses an L-shaped structure, which can easily snag the conductor and ground wire during operation. Therefore, it is very necessary to provide a transmission line drone-based self-locking pulley for hanging and unloading that optimizes the pulley structure, eliminates the need to climb the tower to complete the pulley hanging and unloading work, adopts a self-locking structure, and eliminates the accident hazard of heavy objects falling off. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a self-locking pulley for unloading power transmission lines by drones, which optimizes the pulley structure, eliminates the need to climb towers to complete pulley loading and unloading operations, adopts a self-locking structure, and prevents heavy objects from falling off.

[0004] The objective of this invention is achieved as follows: a self-locking pulley for unloading power transmission line drones, comprising a pulley assembly and a fall-prevention self-locking pulley assembly. The fall-prevention self-locking pulley assembly is located below the pulley assembly. The pulley assembly is connected to the fall-prevention self-locking pulley assembly via copper rivets with drills. The pulley assembly includes a hook, and a locking tongue is provided inside the hook. The outer end of the locking tongue is rotatably connected to the hook via a rotating shaft. A ratchet locking device is provided inside the locking tongue. A wire is provided inside the hook.

[0005] The hook has a fixed seat on the upper outer side, a spring pin inside the fixed seat, a positioning pin below the spring pin corresponding to the ratchet locking device, and a hanging ring above the spring pin. The hook is made of 40Cr material.

[0006] The anti-fall self-locking trolley assembly includes a left hanging plate and a right hanging plate, which have the same structure and are arranged symmetrically from left to right.

[0007] The left and right hanging plates are connected by a hanging beam. A flat washer nut is provided at one end of the hanging beam. A bolt is provided below the hanging beam.

Anti-slip teeth are provided on the outside of the pulley shaft. Bearings are provided on both sides of the pulley. A second stainless steel gear is provided on the outside of each bearing. A bearing spacer sleeve is provided on the inside of each bearing.

[0009] The left and right hanging plates are equipped with spring steel rods on the upper left and right sides inside. The spring steel rods are in the shape of a "7". The flat washer nut, the hanging beam, the left hanging plate, and the right hanging plate are all made of LC4 material.

It is suitable for using a drone to attach and attach self-locking pulleys for transmitting insulating ropes on conductors or overhead ground lines. In use, operators on the ground use a drone to precisely attach the pulley assembly, the fall-proof self-locking pulley assembly, and the insulating rope to the desired work position.

The anti-fall self-locking pulley assembly features gear-driven self-locking, effectively activating the self-lock when a suspended heavy object slides down rapidly, ensuring safe and standardized operation and greatly guaranteeing the safety of workers. 2. By using a drone to lift the wire to the work site, the locking tongue relies on its own weight for self-locking. Furthermore, by using the drone to unload the wire, the lifting ring is raised, releasing the ratchet locking device and opening the hook, facilitating remote-controlled hook retrieval after the work is completed, reducing operational risks and improving efficiency. 3. Relying solely on the ground-based drone and the transfer rope, workers can complete the pulley loading and unloading work without climbing the tower. The self-locking structure eliminates the accidental risk of heavy objects falling.

Adjust the direction of the drone and move the drone horizontally until the wire is hooked into the opening area of ​​the trolley assembly; 3. Operate the drone to lower it. The opposing force generated between the weight of the trolley assembly and the wire causes the locking tongue to rotate through the rotating shaft and finally reach the closed state. At this time, the spring pin is in the extended state under the action of the spring force. With the help of the ratchet locking device, it locks the locking tongue. The cable hanging operation of the trolley assembly is completed through the above steps.

[0040] Steps for retrieving the pulley: 1. Use the drone to lift the hanging ring, pull the spring pin out to the closed state, and the locking tongue will rotate through the rotating shaft under the reaction force of the wire, thus opening the lock; 2. Use the drone to lift the pulley assembly to a safe area above the wire, adjust the drone's direction, and move the drone horizontally to move the pulley assembly away from the wire; 3. Use the drone to descend and return the pulley assembly to the ground. The above steps complete the entire process of hanging the pulley assembly and retrieving the pulley.
